TRUSSED RAILWAY-RAIL.

Specification of Letters Patent.

Patented Dec. 22, 1914.

Application .filedMay 19, 1913. Serial No. 768,461.

To all whom it may concern: I I

Be it known that 1, CHARLES S. CLARK, a citizen of the United States, residing at Duxbury, county of Plymouth, State of Massachusetts, have invented a certainnew and useful Improvement in Trussed Railway-Rails, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being hadflto the accompanying drawings, which form a part of this specification.

My invention has for its primary object to strengthen the ordinary railway rail without increasing the amount of metal therein.

Y I accomplish the foregoing object by rolling or otherwise bending portions of the base flanges downwardly so as to provide the rail with a series of downwardly extending trusses which will increase the effective height of the rail throughout the trussed portion; the trusses being preferably so arranged that they will not interfere with the ties as ordinarily spaced. Byarranging the depending trusses between ties, the trusses may be made to serve as transverse shoulderswhich will abut against the sides of the ties and thus prevent the rails from creeping or moving longitudinally. Therefore,

viewed in one of its aspects, my invention may be said to have for its object so to shape a railway rail that it will be held against creeping without the necessity of employlng separate anticreeping devices. I

The various features of novelty whereby my invention is characterized will hereinafter he pointed out with particularity in the claim; but, for a full understanding of my invention and of its object and advantages, referencemay be had to the following detailed description taken in connection with the drawings, wherein:

Figure 1 is a side elevation of a fragment of a rail arranged in accordance with one form of my invention, and portions of two railway ties. on which the rail rests; Fig. 2

- is a section on line 2-2 of Fig. 1;. Fig. 3 is a plan view of that portion of a rail extending across two consecutive ties, showing a modification; and Fig. 4 is a section on line 4.--4 01 Fig. 3. p

In the arrangement shown in Figs. 1 and 2 of the drawing, 1 represents an ordinary railway rail, while 2 and 3 represent two consecutive ties on which the rail rests. At various points along the rail, preferably on both sides thereof, portions of the base flange 4; are bent down at any desired angle to form depending trusses, 5, the ends of the trusses being joined at the ends to the normal portions of the base flanges by webs or ribs, 6. Wherever one of the depending trusses is located, the effective height of the rail is. increasedan amount equal to the effective vertical height of that portion of the truss lying below the plane of the bottom of the base. The trusses are preferably so disposed that they will be located between the ties as the latter are ordinarily spaced, so as not to make it necessary to change the spacing of the ties or to shape them especially to fit the modified form of rail. In the arrangement shown in these two figures each truss is made substantially as long as the distance between two of the ties so that each entire portion of the rail lying between two ties is made deeper and therefore stronger than the ordinary rail. Any desired relation may be maintained between the trusses on opposite sides of the rail. Thus, in the arrangement shown, that portion of the base flange directly opposite the truss 5 is left in its normal condition while, at a point between either of the ties 2 and 3 and the next tiethere is formed a truss 7 similar to the truss 5.

Not only do the trusses stiffen the rail; but, by allowing the webbed ends to engage with the sides of the ties, the trusses serve effectually to prevent creeping of the rail, the webs thus forming wide bearing surfaces which will prevent the trusses from cutting into the ties.

In the arrangement shown in Figs. 3 and 4 the trusses 8 are madeshorter and also shallower. than the trusses 5, each being conmy invention, I do not desire to be limited to these axact forms; but intend to cover all constructions regardless of the height or length of the trusses, the angle at which they are disposed, or of the manner in which they are distributed lengthwise of the rails, as will be evident from the definitions of my invention constituting the appended claim.

I claim:

A railway rail having portionsof its base flanges bent downwardly to form trusses copies of this patent may be obtained for distributed to lie between railway ties as ordinarily spaced, the trusses on opposite sides of the rail being arranged in staggered relation to each other. 1

In testimony whereof, I sign this specification in the presence'of two Witnesses.
